* Gemini offshore wind farm to have 600 MW capacity

* Production expected from 2023

* Siemens to provide 150 wind turbines

LONDON/FRANKFURT, May 15 (Reuters) - The Dutch Gemini
offshore wind farm project placed a 2.8 billion euro ($3.84
billion) construction and services order with a consortium led
by Canada's Northland Power and Germany's Siemens
.

The 600 megawatt (MW) wind power project will be built in
the Dutch North Sea, 85 km from Groningen, and is designed to
provide enough electricity for 1.5 million people once it
becomes operational in 2017.

The diversified German engineering group won 1.5 billion
euros worth of business from the contract. It will deliver 150
wind turbines with a capacity of four megawatts (MW) and a rotor
diameter of 130 metres each and will maintain the wind park for
15 years.

As part of its maintenance, Siemens will have a dedicated
helicopter and a purpose-built service vessel on standby at the
site.

"Maintenance work can be carried out at almost all times
irrespective of the weather conditions or wave height," the
company said.
